I'm having some problems when using this controls together, i have a small application that i made for a friend that intends to maintain data from people (clients). I used the tab control to separate the type of info, and use a global button to call the TableAdapterManager Update All command (i have 2 more tables in the database that have names of citys and types of professions to make it easy to fill all the data), some times it works others no... "Error Update 0 of 1" The form was built with drag and drop operations...
I was wondering if there was a solution to replacing the tab control's tabs with custom tabs made in Photoshop. I know there are plenty of super expensive programs that can do it, but I was wondering if there was a way to do it programmatically. I was thinking that maybe it could linked in some way with a .DLL?
Private _adapter As New SqlDataAdapter("Select CaseId, CaseNum, DateLoaded, Status1, DateDiff(mm,DateLoaded,GetDate()) as mm From Case_T" _ & ";Select CF.CaseId, CFV.VendorId, CFV.DueDate From CaseFileVendor_T CFV Left Join CaseFile_T CF on CF.FileId=CFV.FileId" _[code]....
Using vb.net 2008 Forms. I have a groupbox consisting of several textbox's and a push button. I put this groupbox in a control collection in order to validate each texbox when the push button is clicked.
The code to do this is as follows: Private Sub bn_updateadditem_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles bn_updateadditem.Click Dim InvalidInput As Boolean = False Controls.AddRange(New System.Windows.Forms.Control() {Me.GroupBox1}) Dim ctrl As Control For Each ctrl In Controls [Code] .....
This worked great. However when I moved this groupbox with all its controls onto a tab, the groupbox contents disappeared from the form after the control collection is created and contents validated (per above code).
I noticed that when using a single letter as the title on a tab of a Tab Control , the tab is bigger that it should . Look on this example :
The above Tab Control behaves normally because the text on each tab is sufficient to keep it big enough . The lower Tab Control , however , has its tabs too big . Is it possible to reduce its width ? I saw there is an ItemSize property of the Tab Controls , but unfortunately I can only modify the height of the tabs . No matter what value I set for its width , the width remains always the same (and larger than it should) ...
Since there doesn't appear to be a built-in ability to change the visibility of an individual tab page within a tab control, is there a generally accepted work around to do so?
How can I control what is filled into the table adapter at runtime? Basically, I have a table full of thousands of rows, and I want to limit this to just 1 row. I want to specify an ID number and be able to pull up that row in the table, and I need to do this at run time. What are my options, and what is the easiest way? I want to make sure the data is still linked to the original row in my database, that way the changes are saved properly.
I have a tab Control with three Tabs.How do I specify that the three tabs Labels should all be equal size and each occupy 1/3 of the total tab width.In a previous product I used in VB6 there was a "Tabs Per Page" property that would do what I want.
I have a setup/configuration utility that I am making. The form is split the left side has a nodeview that allows the user to select what they want to setup/configure, and the right side displays that screen.
I figured the easiest way to switch between those screens is to place them in a TabControl, but I dont want the tabs to display when its compiled. How can I turn off the display of the tabs?
have a datagridview containing 2 tables left joined, so that:table1 LEFT JOIN table 2 ON table1.id=table2.idI get an error whenever I try to edit my datagridview."invalidOperationException was unhandled by the user codeDynamic SQL generation is not supported against multiple base tables."The error points to this line:
da.FillSchema(dt, SchemaType.Mapped) da.Update(dt) << This line 'da = dataadapter
i am creating an activeX control... in this control i want to manage what the tab key does. i may a user interface that allows tabs in the textbox or it might move the user to the next screen. i have everything working in the IDE, but when my activeX is loaded into the 3rd party application the tabs no longer trigger the key down event. i assume this is because the parent application has tab stops is there a way on a control by control basis to stop the normal execution of tabs?
ok i currently have a tab control aka a web browser with tabs but want a close button on each tab i do not want to do a full recoding and i want to know if there is just a simple code to add on to my current tab control my tabcontrol is called tabcontrol1 my web browser name is wb
In VB6, there was an issue of not being able to color just the tabs of the tab control. It appears this is still the case in .net, yes? Does anyone have a way to paint the tabs of the tab control
I use VB. NET 2008. I'm starting to work with the Tab Control and command will want to know about techniques such as adding tabs at runtime using this control.
To illustrate what I'm saying, just take one checked on your browser or in the VB (Start Page, when we add other forms to our project).
I have a application with a tabcontrol. I dynamically open new tabs on which there is a custom control which is made of a graph and a datagridview with data. I fill this from a csv file. when I open few tabs like this my application memory goes over 120 MB. When I remove the tab I call the dispose on the custom control and a dispose for the tab. But the memory stays where it was (120+MB). It goes down only if I minimize the program. And when I show it again its around 10MB.
VB 2005 I have a tab control, with 2 tabs (Tab1 & Tab2), I need to use a textbox from Tab 2 Before I ever select to display it. is there a way to initialize the text boxes in the unopened tabs?
My code is basically a file parser/editor and it handles most files fine as they hold a handful of records concerning family members. However there are a few files that crash when trying to deal with them. Here is the problem.Each family member record creates 3 tabs that hold an average of 3 group boxes each. Each group box holds an average of 3 text boxes.So each member record creates 3x3x3 = 27 text boxes and some files get up to 289 family members which = 7803 text boxes.
The problem is the rare file with 400+ member records = 10,800 text boxes which causes a crash due to using up all the window handles. Each member has a separate tab page (with 3 subpages) but really only a dozen or so member pages are visible in the GUI with scroll arrows to move through them so I was thinking of somehow making the GUI a scrollable window so the tabs get built, displayed and disposed as the user scrolls left and right through the member tabs.
The files are parsed into a 3d list DataList(x,y,z) where x is the page number, y is the group box number and z is the text box number. So all the data is available. The code then traverses MyList and builds GuiList(x,y) where x is the page number and y is the groupbox number with all the textbox.text linked to MyList(x,y,z) locations so all text changes are reflected in the MyList.
I already have a memberCount variable and I am thinking of building, say, the first 30 member tabs with the middle 10 being visible in the GUI. If the selected tab > 20, then dispose of the first 10 tabs and create tabs 30-40.I am thinking I will keep all the member tab pages so I don't have to deal with inserts and indexing problems but just dispose all the group boxes and text boxes for tab pages out of view. I already have a deep clone sub that clones members when the user wants to add a new family member and I am thinking I will have to add something similar when a tabpage is passed in for disposal, it traverses and disposes each text box, then disposes the group box for each group box on the tab page.Additionally, another routine will rebuild the group boxes from the data held in MyList(x,y,z) when a tabpage(x) is passed in.
remove the tabs from the TabControl and just buttons to control which screen is shown.Ive coded a form that uses buttons to hide and show panels but because you cant click buttons in design view, its extremely hard to edit the content in the panels.
I've got a tab control and want to dynamically add tabs depending on the output from a database. I can easily add a new tab, however I want to inherit the controls and layout from the initial tab.
I have 3 controls sharing the same Bindingsource.Each control will require a different parameter for the query call to the DB to populate the proper controls data.However each control is filled with the same data and using one ctrl has the same effect to the thre controls. The controls all mirror eachother.how can i create a new instance of the table adapter?
I have a very large table, and I have a sql data adapter to fill a data table. The user is able to change some values, then saves the changes, at this point i just call the adapter update method (I use the sql command builder to get all the commands of the adapter). What I need it's to make some changes to 4 parameters in the update command, before calling the update command, but I don't see how to do this? Before the update itself, I don't have any values, if I set the parameters (I saw the number of the parameters in the debug mode), before the update, that doesn't do anything, I think they get override in the update method...
I fill a datatable using the dataadapter. and i set the adapter.missingschemaaction = missingschemaaction.AddwithKey. i set the insertcommand,updatecommand and deletecommand for the adapter as well.however, when i click on the datagridview to add new rows a new temporary primary key is not generated in my datatable.I've done this with access and sql server 2005 with no problems. im using MySQL.Net connector 6.1.2
